New Guinea Impatiens plant named ‘Danharpurcrown’

ABSTRACT

A new and distinct  Impatiens  plant named ‘Danharpurcrown’ characterized by having large, round flowers, bicolor purple flower color; green leaves, mature leaf upper surface RHS 147 A; and compact and round plant habit.

Genus and species of the plant claimed: Impatiens hawkeri.

Variety denomination: ‘Danharpurcrown’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens, hereinafter referred to by the cultivar name ‘Danharpurcrown’.

The new cultivar originated from a cross made in a controlled breeding program made by the inventor, Gabriel Danziger, in 1999 in Moshav Mishmar Hashiva, Israel. The female parent is a proprietary cultivar designated E-703 (unpatented). The male parent is a proprietary cultivar designated E-110 (unpatented). ‘Danharpurcrown’ was discovered and selected by the inventor, Gabriel Danziger, as a flowering plant within the progeny of the stated cross in a controlled environment in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by leaf cuttings. The cuttings are apical cuttings; no more than two expanded leaves and three to four immature leaves evident. Asexual reproduction of ‘Danharpurcrown’ was first performed December, 2000, in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new variety is stable and reproduces true to type in successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Danharpurcrown’ which in combination distinguish this Impatiens as a new and distinct cultivar:

-   -   1. Large, round flower;     -   2. bicolor purple flower color;     -   3. green leaves, mature leaf upper surface RHS 147A; and     -   4. compact and round plant habit.

‘Danharpurcrown’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Moshav Mishmar Hashiva, Israel, under conditions which closely approximate those generally used in commercial practice.

Plants of the new Impatiens cultivar ‘Danharpurcrown’ differ from plants of the parents, ‘E-703’ (unpatented) and ‘E-110’ (unpatented), in the following characteristics described in Table 1:

TABLE 1 Female Parent Male Parent New Cultivar ‘E-703’ ‘E-110’ Trait ‘Danharpurcrown’ (unpatented) (unpatented) Flower Bi-color purple, Bi-color purple Red, color RHS 66A and RHS 63A and RHS 42A RHS 80A RHS 80B Plant Height: 15 cm Height: 20 cm Height: 18 cm Size Width: 30 cm Width: 30 cm Width: 30 cm

Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Danharpurcrown’ is cultivar ‘Harmony Dark Betio’ (unpatented). ‘Danharpurcrown’ has larger flowers than ‘Harmony Dark Betio’ and the flower color of ‘Danharpurcrown’ is darker than that of ‘Harmony Dark Betio’.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing show colors as true as is possible with reproductions of this nature. The first photograph shows a top view perspective of a ‘Danharpurcrown’ plant. The second photograph shows a close-up view of a flower, leaves and bud of ‘Danharpurcrown’.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the new cultivar as grown in Moshav Mishmar Hashiva, Israel, under conditions which closely approximate those generally used in commercial practice: day temperature ranging from 20° C. to 24° C., night temperature ranging from 18° C. to 20° C.; fertilized up to a level of 150-200 ppm N, 80 ppm P, and 150 ppm K. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 1:00 pm in a greenhouse. The age of the plant described is 12 weeks.
